Introduction
This document has been prepared to be a harmonized standard to provide one means of conforming to the
essential safety requirements of the Machinery Directive, and associated EFTA regulations. This European
Standard is a type “C” standard as defined in EN ISO 12100:2010.
The extent to which hazards are covered is indicated in the scope of this document.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence over the provisions of other standards, for machines that
have been designed and built according to the provisions of this type C standard.
The requirements of this document are directed to manufacturers and their authorized representatives of
down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular saw benches. They are
also useful for designers.
This document also includes information to be provided by the manufacturer to the user.
Common requirements for tooling are given in EN 847-1:2013.
Electrically driven machines excluded by the scope of this document are covered by the requirements of
EN 61029-1:2000, EN 61029-2-9:2009 and EN 61029-2-11:2009.

1 Scope
This European Standard deals with all significant hazards, hazardous situations and events as listed in
Clause 4 which are relevant to down cutting cross-cut saws and dual purpose down cutting cross-cut
saws/circular saw benches, herein after referred to as “machines”, designed to cut solid wood, chipboard,
fibreboard, plywood and also these materials where they are covered with plastic edging and/or plastic/light
alloy laminates when they are used as intended and under the conditions foreseen by the manufacturer
including reasonably foreseeable misuse.
NOTE 1 For the definition of down cutting cross-cut saws and dual purpose down cutting cross -cut saws/circular saw
benches, see 3.2.2, 3.2.3 and 3.2.4, and for the definition of displaceable machine, see 3.2.8.
This document does not apply to:
— machines for cross cutting logs;
— hand-held motor-operated electric tools or any adaptation permitting their use in a different mode, e.g.
bench mounting;
NOTE 2 Hand-held motor-operated electric tools and saw benches to form an integrated whole with a hand-held motor-
operated electric tools are covered by EN 60745-1:2009 together with EN 60745-2–5:2010.
— transportable machines set up on a bench or a table similar to a bench, which are intended to carry out
work in a stationary position, capable of being lifted by one person by hand i.e. maximum mass ≤ 25 kg.
NOTE 3 Transportable motor-operated electric tools are covered by the requirements of EN 61029-1:2009 together
with EN 61029-2–9:2009 and EN 61029-2–11:2009.
This document is not applicable to down cutting cross-cut saws and dual purpose down cutting cross-cut
saws/circular saw benches which are manufactured before the date of its publication as European Standard.
